I love XS too much hahahhaa

Even with a waterblock over it, it might be just better to just place the waterblock directly on your CPU and forget about the TEC. I am talking about full load temps... On idle, that TEC would bring your cpu to 10C or less. But under load, the heat would be too much, and it would perform bad, and your temps would reach about the same temps you would reach without the TEC.

Now, there are some 400W TEC's that would keep your quad on sub 20C during load. But to cool 400W on the hot side of the TEC, you would need a chiller. And then again, if you put the chiller directly into the CPU, you might get similar results.

That is the problem of the Peltiers, and that is why they are not so recomended. I am curious to see how this V10 with a 75W TEC will do.

That was a nice read STEvil, thanks.
From the results he achieved on a dualcore, it is very possible that system would be able to handle a quad moderated overclocked. But there are 2 large TEC's and 2 TRUE's there. But it might be possible, only if he tests it on quad we would know. On a high overclocked quad, it would fail.
I have played with TEC's before, and I can say, that system holded a low temp on the cold side, because the load of a 45nm dualcore at that vcore and 4GHz is still very low. Once you go increasing the load on the cold side, the TEC will be losing its efficiency very fast. Meaning the hot side needs to be cooled better, or the system will get out of control, and perform worst then the same system without the TEC's. On a quad at 1.6V and 4.5 - 5GHz, things are much different, the heat of the CPU is twice more, and the TEC's fails miserably with cooled with air, no matter what cooler. No aircooler would handle the hot side well, to keep the TEC on the efficiency part of the chart.

If there is no load, you can cool a 2000W TEC with air if you want.
With little load (heat) of a 45nm dual core at 4GHz or so, you can still cool the TEC with air, as that link showed.
But you start raising that load (heat), and you will see how fast the TEC will lose efficiency. And the only way to get it back, is to keep the hot side closest to ambient as possible. And aircooling won't be able to do it, at a certain point.
I say it is impossible to cool TEC's with aircoolers, and use them on high overclocked quads. We are talking about 250W - 300W load from CPU + the TEC load which can be arround 200W LOL! No way to do it with air.

wow people seriously stop whinging...

look if you want this buy it... it may beat TRUE if it does then fair does


if you want to stick to TRUE then fair does do that.

Why :banana::banana::banana::banana::banana: about something like this lol kinda sad... fanboi isk?

There's a link to an IFX14 with TEC on quad in that thread I think.


The point is it is doable, but the efficiency is poor.

I had one of those, great little cooler. Loud bugger though, but other than that it was great.

do people reach 4.2ghs on air with I7 ?
that's 10 watts for every 100mhz

170 watts at 3.85ghz volts at 1.600.

btw i'm already running my phenom II at 3.755ghz @ 1.4875

---

Phenom II looks to be 8.75 watts for every 100mhz

lastly I had a phenom 9850 dumping out heat on my sunbeam CCF in fact the heat sink got up to 41C. right now with phenom II 940 I haven't seen it go above 33C. with the same volts as the 9850.

the old phenom 9850 used a lot more power just for 3.0ghz because I needed 1.4875 volts. (vista 64 bit)

god will you just let the stuff go....o you true users blah blah blah.....stop talking about it if u dont like it....u dont need to spam everytime u see a post u dont like

Some are over 4.6 on air.

290 watts of cooling on AIR! :shocked:
I don't know if that's max volts or now on I7. I know for phenom II it's above what AMD stated as max on air.

I think the TRUE is probably one of best out there. But you need to lap it, and washer mod it to get to that point. Its amazing its been this good for so long.

Ive seen the reviews of the Thermal Lab Baram. Looks to be very similar to a TRUE overall, even showing good improvements using 2 fans. I wish they would get some in the US to buy. Id give it a shot.

I do want to see some results for the new Xigmatek Thors Hammer. 7 heatpipes, 4 8mm 3 6mm. Looks like a winner. Can handle 2 fans. May be the next best thing.

I dont care for the looks of the V10. Somewhat stupid looking IMO. The V8 is a decent air cooler, but huge is the word.

would it be possible to lap down the contact area, until you get a heatpipe direct touch?

You can get to almost HDT...but it'd take you awhile :lol:

How loud is this monster?

All V10 numbers are being withheld until embargo is lifted :S

That's just not fun at all :(

The V-10 is amazing!!! Makes me think that we reaching the limits of air cooling...I mean, carbon nanotubes and 200cfm fans aside, there is not much room for improvement.

The limit isn't reached until watercooling is matched :cool:

Well water can hold a lot more heat than air...so that won't really happen.

Though I feel air is closer to that "limit" than water is to it's own prescribed limit.

Watercooling is just another method of moving thermal energy into the same environment aircoolers dump heat into :cool:

The basic reason it's more efficient is because of the general lack of size limitations for the radiator and because you can use forced flow in the tubing rather than the passive heatpipes we have in HSFs. :yepp:

Someday though....it'll all collapse into basically the same performance envelope (radiator size in aircooling will probably end up being the bottleneck that keeps it from being totally equal) :)

Totally agree. This is one smart guy.

When will we start seeing some V10 #'s? I am not sure if there was a date indicated when people could start posting them.

thanks,
Eddie

Few numbers for the V10 that people might find interesting:

41, 140

(day of the year it launches, MSRP in USD)

But is it possible?

I may try it with my TRUE, sanding it down to the heatpipes.
